Ten Heresies of Finance

I have had the pleasure of reading the (Mis)behvior of Markets, by Benoit Mandelbrot and Richard L. Hudson recently.

Here are the "Ten Heresies of Finance"

1. Markets Are Turbulent

2. Markets Are Very, Very Risky - More Risky Than the Standard Theories Imagine

3. Market "Timing" Matters Greatly. Big Gains and Losses Concentrate into Small Packages of Time

4. Prices Often Leap, Not Glide. That Adds to the Risk

5. In Markets, Time is Flexible

6. Markets in All Places and Ages Work Alike

7. Markets Are Inherently Uncertain, and Bubbles Are Inevitable

8. Markets Are Deceptive

9. Forecasting Prices May Be Perilous, but You Can Estimate the Odds of Future Volatility

10. In Financial Markets, the Idea of "Value", Has Limited Value

Chapter XII: "Ten Heresies of Finance"
Pages 225-252
